Causal ODE package

This is the code repository of the AISTATS 2022 paper : "Predicting the impact of treatments over time with uncertainty awareneural differential equations."

Package and dependencies installation

We support both conda environments and poetry types of environments.

Conda

conda create --name causalode --file requirements.txt

Poetry

Poetry is a python dependencies manager. You can install it following the instructions here.

You can then install all the dependencies at once by running:

poetry install

Attention When using poetry as package dependencies, you'll have to add poetry run to your commands. Example:

poetry run python train_model.py

Run the code

To run the experiments from the paper, you can use the parametrizations below. All datasets are generated on the fly. The different folds were created by changing the seed parameter.

Harmonic Oscillator data set

python train_model.py --N_ts=1000 --batch_size=64 --continuous_treatment=True --embedding_dim=64 --gamma=8 --kl_param=0.001 --logger_type=wandb --max_epochs=2000 --num_samples=5 --propensity_scores=False --seed=44 --sigma_sde=0.1 --static=False --std_dev=False --variational=True

CardioVascular data set

python train_model.py --N_ts=1000 --batch_size=64 --continuous_treatment=True --dataset_name=cv --embedding_dim=64 --gamma=10 --horizon=10 --kl_param=0.001 --logger_type=wandb --max_epochs=2000 --num_samples=5 --propensity_scores=False --seed=44 --sigma_sde=0.1 --std_dev=False --variational=True

Dexamethasone data set

train_model.py --N_ts=1000 --batch_size=64 --continuous_treatment=True --dataset_name=covid --embedding_dim=64 --gamma=10 --horizon=10 --kl_param=0.001 --logger_type=wandb --max_epochs=2000 --num_samples=5 --propensity_scores=False --seed=43 --sigma_sde=0.1 --std_dev=False --variational=True

Process the results and make the figures

We provide jupyter notebooks to process the results of the experiments and generate the figures displayed in the paper.

  • Evaluation CFODE.ipynb

computes the results reported in Table 1 in the paper.

  • Figure 3.ipynb

creates the Figure 3 in the paper.

  • CostTreatment.ipynb

contains the experiments of section 5.3 about improving the treatment strategies with the derived uncertainties

  • OOD.ipynb

contains the scripts for the experiment on out-of-distribution sampels as reported in the Appendix.

Logging

All experiments have been logged with Weights and Biases but we also support MLFlow and Tensorboard. You change the type of logger by setting the --logger_type option.
